ZW32-24 Outdoor Vacuum Circuit Breaker（ZW32-24F、ZW32-24、ZW32-24G ）is a control and protection device in the rated voltage 24KV, 50HZ AC three-phase high-voltage distribution network. Mainly used for breaking and closing load current, overload current and short-circuit current in power lines. It is suitable for protection and control in substations and power distribution systems of industrial and mining enterprises. This circuit breaker adopts column type, dry structure, reliable insulation, long electrical life, maintenance-free, especially suitable for the requirements of frequent operation places. It is more suitable for installation and use in rural power grids with weak overhaul and maintenance capabilities. It can also be used as a segment switch of the power grid. After adding a controller, it can realize the automation of the distribution network.
It is an outdoor switchgear with three-phase AC 50Hz and rated voltage of 24kV.
It is suitable for switching loads of different natures and frequent operation occasions. Construction and renovation of electrical equipment such as railways. This product is the first 24kV outdoor high-voltage switchgear
that was successfully developed on the basis of domestic raw materials and processes by absorbing foreign advanced technology and suitable for my country's national conditions. It has its own intellectual property rights and
a number of patented technologies, filling the domestic 24kV voltage level. Compared with other similar products in the world, it has the characteristics of miniaturization, maintenance-free and intelligent. At the same time,
the product has no pollution to the surrounding environment and is a green and environmentally friendly product.
